I have a 2002 Pontiac Montana. About once a week or even less, when I am driving on an open highway, it seems like a gust of wind come (except I am not sure there is wind). and the montana seems to jerk or move. I feel like I have totally lost control, but then I look and nothing has happened. At first I thought I needed new tires, so I got new tires. But it seems to be getting worse. Tonight I was driving home and it was windy. I had driven for about 10 minutes then I accelerated up to 100km. My vehicle started to move almost like I had a flat tire or there was ice under. My son said that he could feel it.
I am not sure if this is normal because I am driving on an open highway or if this is something going on my vehicle. I would take it in, but it happens very irregularly.
Anyone Montana owners have any insight????
Thanks Just Me
